BEST MODE FOR CARRYING OUT THE INVENTION An embodiment to which the present invention is applied will be described below with reference to the drawings. FIG. 1 is a perspective view of an erroneous operation prevention mechanism for explaining an embodiment of the present invention. In the figure, reference numeral 1 denotes a device body, for example, a device (handy terminal) body such as a battery-powered portable wireless device or a laptop personal computer. However, only the configuration in the vicinity of the battery mounting portion is shown, and the configuration shown in the figure is the battery insertion portion 2. 2 is a front view when the lid is closed, FIG. 3 is a plan view, and FIG. 4 is a side view.

The erroneous operation preventing mechanism of the present embodiment has a lid member 3 as a first mechanism, a shutter 4 as a locking means, and a second mechanism.
The switch drive plate 5 which is the mechanism of the above, and the switch 6 which is the detection means. The lid member 3 functions as a lid that covers the above-described battery insertion portion 2, and when the lid member 3 is closed, it has a handle (not shown) and is closed in the direction of the arrow shown in the figure. In addition, a rotary lock releasing member 7 is arranged at substantially the center of the lid member 3. The lock release member 7 is provided with a locking portion 7a, and the tip of the locking portion 7a is brought into contact with the shutter 4 by rotating the lock releasing member 7 around the shaft 7b in the arrow and'directions. .

The shutter 4 has an arrow centering on the shaft 4a,
The key-shaped lock portion 4b is formed at the tip of the lock portion 4b. Also, the lock release member 7
The tip of the locking portion 7a of the above is in contact with the lock portion 4b. For example, when the locking portion 7a is rotated in the arrow direction, the shutter 4 is rotated in the arrow direction to unlock the shutter 4. It is a composition.

A lock pin 5a and a switch drive lever 5b are erected on the switch drive plate 5, have a rotary shaft at a position (not shown), and are rotatable in the arrow and'directions. When the shutter 4 is in the lock position, the switch driving plate 5 cannot be operated (moved) in the arrow direction because the lock portion 4b of the shutter 4 contacts the lock pin 5a.

When the switch drive plate 5 can be operated (when the lock is released), it can be driven in the direction indicated by the arrow, and the drive portion 5b 'at the tip of the switch drive lever 5b moves the knob 6'of the switch 6 into position. It is configured to be driven in the arrow direction.

The operation of the erroneous operation preventing mechanism having the above structure will be described below. Hereinafter, description will be given separately for the case of mounting the battery and the case of removing the battery. First, the case of mounting a battery will be described. However, in this case, the lid member 3 is first opened as shown in FIG. 1, and the switch driving plate 5 is also in the state shown in FIG. In this state, as shown in FIG. 1, the lock pin 5a of the switch driving plate 5 is in contact with the lock portion 4b of the shutter 4 and cannot operate.

First, the battery is attached to the apparatus main body from the battery insertion portion 2. Next, the lid member 3 is rotated in the direction of the arrow to close the battery insertion portion 2. After that, when the lock release member 7 is rotated in the arrow direction, the locking portion 7a contacts the lock portion 4b of the shutter 4, and the shutter 4 is rotated in the arrow direction to unlock the switch drive plate 5.

Next, when the switch driving plate 5 is operated in the arrow direction, the shutter 4 is unlocked, so that the lock pin 5a moves in the arrow direction without contacting the lock portion 4b. Switch 6 on,
An ON signal is output to a control circuit (not shown). The control circuit knows from the ON signal that the battery has been installed in the device.

By the above operation, the battery is mounted on the main body of the apparatus, the ON signal of the switch 6 is always output after the battery is mounted, and the control circuit can know the mounting of the battery by this operation signal.

Therefore, for example, even if the switch driving plate 5 is operated without closing the lid member 3, the switch driving plate 5 cannot be operated in the arrow direction. That is, even if the switch driving plate 5 is operated, the lock pin 5a comes into contact with the lock portion 4b and cannot be operated in the arrow direction. Therefore, the lid member 3
The switch drive plate 5 cannot be operated unless the switch is closed, and the switch 6 does not output an ON signal, and the device does not operate.

The switch 6 is turned on even if the lid member 3 is closed without operating the battery and the switch driving plate 5 is operated. However, since power is not supplied from the battery to the switch 6, the apparatus operates in this case as well. do not do.

Next, the operation of taking out the battery mounted in the apparatus will be described. In this case, first, the switch drive plate 5 is pulled in the direction of the arrow ', and the switch 6 is turned off. By this processing, an OFF signal is output from the switch 6 to the control circuit, and the control circuit knows that the battery will be taken out thereafter. Therefore, this signal allows the control circuit to safely retain the data if the battery is removed. For example, when an off signal is input,
The control circuit saves the data and programs stored in the RAM or the like and prepares for the case where the battery is taken out. Such processing has a certain period of time after the OFF signal is output from the switch 6 until the battery is actually pulled out, and it is sufficiently possible for the control circuit to carry out data preservation processing during this time.

Therefore, thereafter, even when the lid member 3 is opened and the battery is pulled out, the data is safely held by the above processing, and the data is not lost and the program is not damaged.

[0027]

According to the present invention, when a battery, a memory card or the like is attached to the apparatus, it can be attached only after the lock is released, so that an erroneous operation can be reliably avoided.

Further, when the battery, the memory card or the like is taken out from the device, the taking out process is known in advance, so that the data or the like can be safely saved.
